III. OPERATIONAL CHECK
1. Install eight AA batteries in the transmitter, referring to the radio system’s instruction manual.
2. Review Fig. 5 to become familiar with your airborne radio components. Following are descriptions of these
components.
Auto Cut-off:
This device cuts-off power to the motor unit when the battery’s voltage starts to drop.
This allows the battery to continue to power the radio for several minutes after the motor quits.
There is a 10 amp fuse which protects the system from overload.
Receiver:
Receives the radio commands from the transmitter and sends them to the Servos which converts the
command to motion which, in turn, moves the rudder or elevator.
Power Switch:
Turns the power on to the whole system.
Start Button:
When pushed, this button starts the motor unit running. The motor will run until either the Power
Switch is turned off or the Auto Cut-off device cuts off power to the motor.
NiCd Battery:
Rechargeable battery pack that provides power to the motor unit and the radio system.
Motor Unit:
Contains a DC electric motor and a propeller that provides the thrust for the airplane.
3. Turn the transmitter on and then the receiver. Refer to Fig. 6.
Move the stick right and make sure rudder moves to the right.
Move the stick left and make sure the rudder moves left.
Move the stick upward and make sure the elevator moves down.
Move the stick downward and make sure the elevator moves up.
Also check for the proper amount of throw and make sure the rudder and elevator are in neutral when the stick
and the trim levers are in the center.
4. Hang on to the airplane and press the Start Button. The motor unit should come on. Make sure the propeller is
trying to pull the airplane forward. Stop the motor by turning off the power swich.
You are now ready to go flying!
